\title{Support for Functions  for smoothers}
\description{
 Those functions  are support for the functions  \code{pb()}, \code{pbo()},  \code{ps()},  \code{ridge()},  \code{ri()},  \code{cy()},  \code{pvc()},  and \code{pbm()}.
The functions are not intended to be called directly by users. 
}
\usage{
gamlss.pb(x, y, w, xeval = NULL, ...)
gamlss.pbo(x, y, w, xeval = NULL, ...)
gamlss.ps(x, y, w, xeval = NULL, ...)
gamlss.ri(x, y, w, xeval = NULL, ...)
gamlss.cy(x, y, w, xeval = NULL, ...)
gamlss.pvc(x, y, w, xeval = NULL, ...)
gamlss.pbm(x, y, w, xeval = NULL, ...)
gamlss.pbz(x, y, w, xeval = NULL, ...)
gamlss.pbc(x, y, w, xeval = NULL, ...)
gamlss.pbp(x, y, w, xeval = NULL, ...)
}

\arguments{
  \item{x}{ the \code{x} for function \code{gamlss.fp} is referred to the design matrix of the specific parameter model (not to be used by the user)}
  \item{y}{the \code{y} for function \code{gamlss.fp} is referred to the working variable of the specific parameter model (not to be used by the user)}
  \item{w}{ the \code{w} for function \code{gamlss.fp} is referred to the iterative weight variable of the specific parameter model (not to be used by the user) }
  \item{xeval}{used in prediction}
   \item{...}{further arguments passed to or from other methods.} 
}

\value{
All function return fitted smoothers.
